I used to work with Tony Butler at Marconi Avionics in Basildon in the 1980s, but lost touch with him after we both moved jobs to other companies. Tony was an AEO ex Vulcan air crew, and his name (Flt Lt A A Butler) is stencilled on the door of XJ824 at Duxford - along with Martin Withers' - as he was one of the crew for her last flight. If anyone knows Tony's current whereabouts I'd really like to get in touch with him as we had a number of interests in common, and I still owe him a drink for teaching me sufficient morse code during lunch hours at work to obtain my radio amateur's licence
